    The place where I got my installation for my breathalyzer very poor instructions how to start the car. Five minutes wasn’t even granted to me to explain anything I felt like I was in a factory and just going down the line spending $180 for an install and I got no information except for a big packet and told me to go home and read it. Not very user-friendly they sent me on my way. I needed instructions on what all. The dues and don’ts very poor representation!!!!! Would never suggest them to anyone. I feel they sucked.!! So I’m revising my review! I got ahold of Isaias from Intoxalock n he was awesome ! He helped me with all that I had mentioned before! He took he’s time exceptionally awesome! I recommend Intoxalock to everyone. But he really made it. Awesome made me feel like I wasn’t on an assembly line. Thank you. I appreciate you.

Frequently Asked Questions About Intoxalock Ignition Interlock

How does an interlock device work?

An ignition interlock device (IID) is a small breathalyzer installed in your vehicle to prevent it from starting if alcohol is detected on your breath. Before driving, you'll blow into the device. If your breath alcohol concentration (BrAC) is below the programmed limit, the car starts. Periodic retests occur during your trip to ensure continued compliance.

What is the cost of an ignition interlock device?

The installation of an ignition interlock device, often called a car breathalyzer, typically costs between $70 and $150. This one-time fee is paid at the start of your lease and covers the service center's labor to install the device in your vehicle.
